| ViewDescriptor | | final public class ViewDescriptor extends TupleDescriptor implements UniqueTupleDescriptor,Dependent,Provider(Code) | | This is the implementation of ViewDescriptor. Users of View descriptors
should only use the following methods:
- getUUID
- setUUID
- getViewText
- setViewName
- getCheckOptionType
- getCompSchemaId

| isValid | | public boolean isValid()(Code) | | Check that all of the dependent's dependencies are valid.
true if the dependent is currently valid |
| makeValid | | public void makeValid(LanguageConnectionContext lcc) throws StandardException(Code) | | Attempt to revalidate the dependent. For prepared statements,
this could go through its dependencies and check that they
are up to date; if not, it would recompile the statement.
Any failure during this attempt should throw
StandardException.unableToRevalidate().
exception:
StandardException - thrown if unable to make it valid |
| prepareToInvalidate | | public void prepareToInvalidate(Provider p, int action, LanguageConnectionContext lcc) throws StandardException(Code) | | Prepare to mark the dependent as invalid (due to at least one of
its dependencies being invalid).
Parameters:
action - The action causing the invalidation

p - the provider
exception:
StandardException - thrown if unable to make it invalid |
| setUUID | | public void setUUID(UUID uuid)(Code) | | Sets the UUID of the view.
Parameters:
uuid - The UUID of the view. |
